GAS BURNER.

Application lecl March 31, 1921. Serial No. 457,208.

To @ZZ 'whom t mag/concern.'

'Be it known that I, JoHNFns'rA, a citizen 'of the United States, and residing at Brooklyn,` Kings County, N ew York State, have invented certain new and useful Improvements in Gas Burners, of which'the following isa specification.v f l This invention relates to gas burners and more especially to that type of burners used in connection with a mantle of incandescent material to produce a radiant effect, and the object of the invention is to provide a burner with a plurality of nipples which may all be used or a part of the whole used and the reduction of use will not interfere with the incandescent action of the ire clay, asbestos or other similar material of which the mantle is composed.

-These and other objects and details of the invention are more fully described in the following speciiication, sety forth in the appended claims and illustrated in the accompanying drawings, wherein:

Fig. 1 is a plan view of the burner.

Fig. 2 is a horizontal sectional view through line 2-2 of Fig. 3.

Fig. 3 is a vertical sectional view through line 3 8 of Fig. 2.

Fig. 4 is a cross sectional view on the line 4 4 of Fig. 8.

Fig. 5 `is a sectional detail of the cock.

In the use of gas heaters of the radiant type there is serious danger of incomplete combustion and consequently the appearance of the lighted heater is seriously affected when the gas supply is reduced and the mantle ceases to be incandescent.

In the present invention the burner ports are so controlled that part of them may be shut olf entirely while the remainder receive a full supply of 'gas and the incandescentmaterial will receive its necessary flame at that point.

As heretofore constructed burners of this type could be turned down only to limit the gas supply and this would leave the heated material with less flame than necessary for incandescence, causing incomplete combustion and marring the appearance of the heater.

In accomplishing these objects the burner comprises supply pipes 5 and 8, mixing tubes 6 and 7 and a vapor supply chamber 9, the latter having a plurality of nozzles 10 fitting in openings 11 in the top of the tube and be ing located directly over tube 7.

i A gas supplypipe 12 hasthe two-way `cock 13 and the two branches 14E and 15 entering* the respective mouths of the pipes 5-v and 8k and each having any air shutter 16 thatv is` ustable on its pipe to regulate the amountl ad] of air admitted to the tube. l

`It will be seen in Fig. 5 that the located as to supply'an equal 4amount of gasto eachy pipe, but a quarter turn 'of theplug. closes one of the branches and leaves the other open as shown in Fig. 5.

In Figs. 2 and 3 it will be seen that the pipe 5 communicates with the tube 6 through the openings 17 and 18 at each end while pipe 8 communicates with tube 7 at the central opening 19.

Adjacent the tube 6 and beneath the supply tube 9 the tube 7 is divided so that the supply oi gas from the@ pipes 5 and 8 are separated by the partitions 20 at each end of the tube 7 and in the wall 21 that separates the latter tube from chamber 9 are openings 22 for the gas from pipe 5 while in that portion of tube `9 between the partitions 2O are openings 23 for gas from pipe 8.

Provisionsare thus made by which the end nipples at each extremity of supply tube 9 are fed Jfrom pipe 5 while all of the intermediate nipples are supplied from pipe 8.

Any number of nipples that may be desired are separatd and fed by the respective p supply pipes but the t arrangement shown provides a very harmonious grouping of jets to produce an agreeable lighting effect, either as one central group or two end groups.

In case, therefore, that the temperature is reached in a room, the heat may be reduced so as to maintain an unvarying temperature to counteract the outside cold by turning the cock 13 to cut off either one or the other of pipes 14 or 15.

It is obvious that the supply tube may be again Idivided to ali'ord other Variations, the cock being correspondingly altered, and that the device may be otherwise modified and arranged without departing from the essential features above described or from the scope of the appended claims.

What I claim as new is:

1. In a gas burner, the combination of a plurality of gas supply pipes arranged bef sides each other horizontally, an elongated burner pipe parallel with and above the supply pipes and having nipples, partitions in said burner pipe, a group of nipples adapted to communicate with a supply pipe, and an cock -is so intermediate pipe between thewemaining a, y i i nipples. and thei other supply pipe.

2. In a gas burner, the combination of a lnipples for the burner pipe, means affording communication between 'a central :group of nipples With one of the supply pipes, and an intermediate pipe With chamberv for the other supply lpipe" and adapted to deliver the gas to end'groups 'of burners. V i

3.r In a as burner, the combination lot va plural-ity loflhorizontally disposed gas supply pipes on the same 'plane, an elongated burner pipe on a plane above the supply pipes and divided by partitions into end and middle `sections,-a mixing tube beneath 'the' middle section and communicating with the latter and one of the supply pipes, asecond mixing tube communicating with the end pipeI sections and a second supply union of the branches, air shutters on the branches, a mixing tube for each branch, a supply tube having' outlet nipples and division Walls, and communicating tubes connecting the mixing tubes with separate divisions of Athe supply tube.

In testimony whereof, 'I have signed` my name to this specification this-th day of March 1921.

' JOI-IN FESTA.
